For those of you who craft

How many Demonic Essences do you save up before you go on a crafting spree? I seem to be unable to manage the patience to save more then 10 before I pull the trigger, but I've read some people saying they saved up 300 at a time before they'd craft. Sooo, how many do YOU save up?

I can never hold on to more than 40 or 60 Demonic Essences at a time before I craft them all. It also doesn't seem to matter how good my current item is, it can always be just a little bit better. I should start saving them for my rising alts, though.
